Application filed September 23, 1913. Serial 110,791,406.

To all whom it may concern:

Be it known that we, EDWARD A. JoNEs and JOHN E. JoNEs, citizens of theUnited States, residing at Scranton and Throop, respectively, in thecounty of Lackawanna and State of Pennsylvania, have invented certainnew and useful Improvements in Graphite Lubricators, of which thefollowing as a specification. I

-Our invention relates to new and useful improvements in automaticlubricators, the

object of our invention being to provide a lubricator for feedinggraphite or any lubricants manufactured in solid form to the valves ofsteam engines, the pistons of engines or any other moving partsforvwhich' such lubricant may be intended.

Afurther object of our invention is to construct a lubricator "by meansof which stick graphite may beground and fed to the parts to belubricated together with lubricating oil, the graphite being ground andthe oil supplied thereto after it is ground and before it passes to theparts being lubricated. p a A still further object of our inventionis toprovide a steam jet adapted to work in conjunction with the grindingmechanism,

so arranged that the steam supply passes with the graphite and oil tothe engine.

A still further object of our invention is to provide means whereby anymoving part of the engine being lubricated may be employed to actuatethe grinding mechanism of-the lubricator. And, a still further objectofour invention is to provide means whereby the quantity of graphiteground.

and fed to the machinery may be varied at will.

Vith these and other objects in View, our

invention will be more fully described, illustrated'in the accompanyingdrawings and then specifically pointed out in the claims which areattached to and form a part of this application. I r i For a fullunderstanding of the invention reference is to be had to the followingdescription and accompanying drawing, in which p I Figure 1 is asectional. View of a conventional form of steam engine, showing themanner of employing our lubricator to supply graphite and oil to theslide valve controlling the admission ofcsteam to the cylinder. Fig. 2is a vertical sectional view of our lubricator proper'taken upon theline 2-2,of Fig. 3. Fig. 3"is a transverse sectional view on the line 33of Fig.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of. the accompanying drawingsby the same reference characters;

Referring more specifically to Figs. 2 and 3 of the'drawings it will beseen that our improvedlubricatorincludes a body proper formed in twoprincipal parts :10 and 11. The body portion 10' is tubular-inshapethroughout the greater portion of its length, being externally threadedat jone 'end,v as shown at 12for threaded engagement in the wall of thesteam chestfior other similar structure and being-provided intermediateits length with a laterally directed, externally threaded-nipple 13 toreceive an oil 'cup shown conventionallyin Fig. 1, at 14'.

The upper end of. the lower body memberI-O is enlargedto provide acircular housing 15,

-eccentrically located with respectto the tubu 'lar portion and havinganupstanding circumferential flange 16 provided with external threads.The upper portion 11 ofithe body ofthe lubricator includes a tubularpart 17 adapted: to extend in a line with -the.-tubu-' lar portion .10and'an exteriorly formed .ex-

tension 18 providing a cap for the housing '15 and coacting therewith toprovide a chamber "19. The circumferential edge of this extension, inconnection with a portion of the edge of the tubular part 17 provides aflange which is interiorly threaded for threaded engagement about'theflange "16. of the housing 15, and both the tubular part '17 andextension 18 are providedwith an inwardly directed flange 20 which seatsupon the upper'edge of the flange 16 when the parts are assembled. Thetubular part 17 at its lower end' is'provided'with an inwardly directedcircumferential flange 21,

thepurpose of which will be hereinafter ex-' Both the above describedparts are preferably cast or otherwise formed of brass or other suitablematerialand cast integrally withthe extension 18 is adiagonally d1sposedjet nozzle 22 which extends through the wall 18 and has its outerend'externally threaded as at 23 to receive a steam supply pipe. Theinner end of this nozzle is directed toward the lower end of the tubularpart 17 of the upper body member 11.

The upper body member 11 is 'provided'adjacenfl its; upper" end with anencircling shoulder 24 and is threaded externally beyond the shoulder toreceive a cap 25, the edge of which engages against the shoulder 24 whenthe cap is in place, this cap preferably extending a considerabledistance above the upper end of the body member and being providedinteriorly with asocket forming a continuation of the bore of the bodymember.

The housing is provided centrally with a packing boX 27 having the.usual packing gland 28 and packing nut 29. A shaft 30 extends throughthis packing boX into the lower portion of the chamber 19 and secured inany suitable manner upon this shaft and against rotation independentlythereof is a grinding disk 31. This grinding disk ispreferably roughcast and fits loosely in the housing 15, extending by one peripheraledge across the lower portion of the tubular part 17 of theupperbodymember 11.. The disk is provided with a plurality of perforations 32,means of which the grinding is accomplished, as will be later explained,and is formed upon its lower face with a boss 33 which seats upon theinner face of the housing 15 to support the disk in slightly spacedrelation thereto. A 001- lar 34 surrounds the shaft above the disk andis held against displacement by a cotter pin 35, this pin and collarholding the disk against longitudinal movement upon the shaft.

, The graphite employed in this lubricator is supplied in stick formandthe stick is placed in the upper bore of the upper body portion 11 ofthe lubricator, supportedbv its lower end upon the upper face of thegrinding disk 31 and properly centralized in the bore of the body memberby the flange 21 at its lower end, and at its upper end by thedownwardly directed circumferential flange 36 of a follower '37. Thisfollower is provided centrally with an upwardly directed pin 38 forminga handle by means of which it be raised from the 'body of the lubricatorand also a support for radially slotted weights 39 by means of whichpressure upon the stick of graphite maybe regulated, but one of theseweights being shown. The pin 38 preferably terminates at its free end inan eye 40 in order that it may be raised bya hook. or other suitableinstrument after the graphite stick has been entirely used. l

The free end of the shaft 30 extends considerably below the packing boX27 "and a lever arm 41 is secured to the free end of this shaft by aset-screw 42 in such a manner that any swinging of the lever-arm in a'horizontal plane will cause an oscillatory fjrnoven'ient of thegrinding disk 31. This fleyer arm is provided adjacent its freeend withaplurali'ty of spaced apartbores 43 for adjustable connection to a linkor any suitable operating mechanism for transmitting power from somepart of the machine b'eing lubricated to the lubricator.

For the sake of a clear understanding of the operation of our improvedlubricator we have illustrated the same in Fig. 1 in connection with aconventional form of steam engine, indicated as a whole by the numeral44 and including a steam chest 45 having a cap-plate 46 through whichthe threaded end of the lower body member 10 is passed, a binding nut 47threaded upon said end being turned against the cap-plate when thelubricator is in place. When so mounted a pipe 48 leading from anysource of steam supply is connected to thejet nozzle. 22 in order tosupply the requisite steam to the lubricator.

The lever-arm 41 may be swung by means of any suitable mechanism formingsome part 'of the engine such as the valve-stem 49. In the present.instance, this connection includes a bracket 50 clamped by one end aboutthe valve-stem, and by its other end to alink 51. This link extends in ahorizontal planeand its opposite end is bifurcated to provide spacedears 52 extending one, above and one. below the lever-arm 41. A bolt '53passes through perforations formed in these ears and one of theseperforations 43 of the lever-arm pivotally connects the link to thelever-arm. It will be clear that the reciprocation of the valvestem 41will cause reciprocation of the link 51 and that this movement of thelink will be transmitted by the lever-a=rm 41 to oscillate the grindingdisk 31.

In operation a sti k of graphite is positioned in the boreof the upperbody member as shown at 54 and the steam is supplied through the, pipe48. Inasmuch as the graphite is held, by the follower and its weightjorweights against the upper face of the disk31 which constantlyoscillated,

as previously described, it will be clear that 1 the disk willconstantly grind away graphite from the lowerend of stick. The steampassing through the steam jet 22 strikes against the upper face, of thegrinding disk an'dalso against the lower portion of the 1 tubular part17 and serves the double funo tion of forcing the ground graphitethrough the perforations of the disk into the lower body member and ofsomewh at heating the disk and tubular part 17 of the body inemher, tothus facilitate the grinding action. The ground graphite falling throughthe lower body member 10 is met by oil from the oil cup 14 and the mixedgraphite, [steam and oil pass into the steam-chest 45. til leans isprovided for regulating ithe proportion of steam supplied to thequantity of'g'r'aphite ground, which lattei may be controlled by meansof the weights 39. he oil cup 14 should be of such a type that thequantity of specific details of construction described in oil flowingtherefrom. may be readily ad justed- It will therefore be clear that theexact proportions as well as the amount of steam, graphite and oilsupplied to the moving parts of the engine may be accurately regulated.

Although we have illustrated the lubri cator as employed for lubricatinga slidevalve of a steam engine, it will also be apparent that it may beemployed for lubricating any other types of engines and moving parts ofmachinery. It will furtherbe clear that the construction admits of manyminor charges, and for this reason we do not wish to limit ourselves inany way to the the drawings, as any desired changes, with in the scopeof the appended claims, may be made, without in the slightest degreedeparting from the scope of our invention.
